ence being had to the accompanying drawing and to the letters of reference marked thereon which form a part of this specification.

. The nature of my invention consists in the construction and arrangement of a steam vacuum -pump, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which Figure 1 represents a front view, and Fig. 2 is a plan view of my pump. Fig. 3 is a section through the discharge-pipes. Fig. 4 is a section through the cylinders.

A A represent two cylinders, into which the water is received from the suction-pipe B, and from which it is discharged by the steam pressin g on the water up into the column-pipe O. The upper end of each cylinder, or the top cap, is made conical, so that the steam upon enterin g in the center of .the same will not have to expand over the whole diameter of the cylinder before it begins to start the water but it starts the water slowly as soon as the steam enters the cylinder and gradually gets the water in motion. The bottom or lower cap of each cylinder is funnel-shaped, as shown, so as to ofl'er the least resistance in discharging the water from the cylinder. B B are the suction or tail pipes, provided each with a valve, 0, and connected by a pipe with the cylinders.

These connecting-pipes are not shown in the the water-cylinders, so that too much waterneed not be taken from the discharge water to condense the steam in the cylinders, the object being to condense all the water in the cylinders and form a vacuum 'to suck the water up into the same, from whence it is discharged into column. The discharge-pipes O (l are each provided with a valve, d, connected by valve-stems with the ends of a lever, D,which is by rods 6 e connected with a similar lever, D, above. to each cylinder, and each branch provided with a stea1n-valve,f, connected by its stem with the lever D. G G are two pipes, each provided with an injection-cock, h, and arranged as shown to take the water from one cylinder to the other, it so desired, instead of from the column, thereby relieving the pressure on the check-valves of the weight of water in the column. 9 g are perforated distributers at the ends of the pipes G G in the interior of each cylinder, for distributing the injection water. H H are the injection-pipes connecting the cylinders or the pipes G G to the water column, each of said pipes being provided with a cock, is, for regulating the supply of injection water. In the top of each cylinder A is a plate, I, for spreading the steam, so as not to force down into the water. J J are cooks for blowing off from the two cylinders. Steamgauges are to be attached to each steam-pipe close to the point where they enter the I cylinders. An aircock is to be placed in the tail or suction pipe B for the purpose of allowing a portion of air to be taken into the cylinders, so as to prevent the cylinders from becoming too full of water, and also for having a film of air between the steam and water when the steam comes in contact with the water. This cock can be regulated so as to admit more or less air, as the distance of the Water to be pumped is more or less from the pump, as more air is admitted when the water is clos than when further ofi'.

The operation of the pump is as follows: Steam being admitted through the pipe to the steam-valves ff the lever D is raised, admit ting steam into one of the cylinders. The cylinder being full of steam, as indicated by the steam-gauge, the steam-valve is closed and injection opened, which condenses the steam in the cylinder, forming a vacuum, causing the water to flow up the suction-pipe into the cylinder. The lever D then being raised at the other end acts in the same manner in the other cylinder, and so-worked by hand alternately until the cylinders become full of water from the suction-pipe. Then, on the water being E is the steam-pipe, branchingindischarged at each stroke through the valves d d (the levers D and D being connected) into the column-pipe, as soon as the water is all discharged as far as the valve (1 the pressure on the same causes it to close, thereby also closin g the steam-valve and opening the valves on the other side, and so continues.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, i=

1. The cylinders A A, constructed as described, the top cap being conical and the bottom cap funnel shaped, and provided with plates I I, in combination with valves ff (1 d, all arranged to operate as set forth.

2. The combination, with the cylinders A A, of the steam-valves ff and discharge-valves d d, constructed and arranged as described, and operating substantially as and for the purposes herein set forth.

3. 1 claim the arrangement of cylinders A A with conical top and bottom pipes Gr G H H, provided with suitable cocks connected with the column-pipe, substantially as described.

4. The perforated distributers g g at the end of the pipes G G, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signature in the presence of two witnesses.
